im building a b18b and i was looking at the crower cams and im not sure, what duration and lift would b ok to put in with out having a tune done. i do not have access to a tune

 

Then don't get them because the answer is "none".

 

so no upgraded cams can be ran with out a tune?
and what other upgrades could i do with out a tune ?

 

Nothing. I don't even know why you're attempting to "build" it if you have no intentions of getting it tuned. Do you even know what that entails?

 

i dont understand...i was told it wouldnt require a tune as long as it wasnt to much of a lift..that was quoted by a sprint car motor builder

 

how much is a tune

 

Then why are you asking? You have a sprint car motor builder as a resource.

You change the internals of an engine that far from stock and expect the stock ECU to be able to compensate?
You have much reading and planning to do.

 

i did ask him and his exact words were not to do to much more of a lift cuz then i will need a tune..so im tgrying to double check from honda owners

 

You can't run any of that aftermarket stuff without a tune. I don't know how he could be so vague if he has done this on a Honda before. You think he would know exactly huh?

Possibly there are other stock B-series cams you could use but that's your homework to find out if and which.

 

so then i will look into b16

 

I didn't say B-16 specifically. I said B-series.

Stop. Just stop. Stop ******* with motors, stop trying to build anything. Pick up a service manual or two. Read them. Open the FAQ's sticky. Read it all. Start doing some learning. You can't just go at it with some tools and random parts - it doesn't work that way.

Learn what lift and duration mean for cams. BC cams are long, and lopey. Like grumble has already tried telling you, any aftermarket cam will require a tune.

 

So which one of those cams equates to your engine builders definition of "not too much"? Maybe I'll just pick one and you can run with it because some stranger on a forum said so? What if I, or anyone else, give you the wrong advice? How would you know?

 

Any cam you get is gonna need a tune AND retainers/springs. You also need to know if its a turbo or NA cam and what supporting mods you MUST have to run it

 

yea bro only thing you might not need a tune is a intake,header exhaust etc...anything internal even cams would need a tune,,,they run about 300 ...not expensive at all.

 

+1

 

if you don't have access to a tune then don't bother doing anything to it, just leave it stock or just buy a more powerful stock engine, and if you still persists on building then buy yourself a hondata, aem, or neptune research and play with it at your own risk.
